PSEMI PE42445 and PE42446 SP4T HaRP technology-enhanced SP4T RF switch features industry leading broadband frequency coverage of up to 8GHz. The PE42445 high-isolation 3x3mm package and PE42446 high-isolation 4x4mm package switches deliver high linearity and best-in-class isolation performance, essential in 5G base stations. Devices integrate seamlessly into 4G and 5G base stations and mMIMO architecture, providing digital pre-distortion (DPD) feedback loops and transmitter monitoring signal paths to prevent interference and maintain signal integrity, given massive MIMO applications. Product’s high reliability and extended operating temperature range allows them to be used in a wide variety of applications, including DPD and VSWR monitoring, portable wireless radios, repeaters and E911 systems, and test and ATE equipment. Offered in compact LGA packages, devices feature high linearity, extended operating temperature and best-in-class isolation and insertion loss performance, ideal for 5G base stations and mMIMO architecture.
